Bot. Calif. I]. 279. (To this species is referred Deyeuxia pur-

9000 ft. 
The specimens are exactly like the eastern plant with the awn 
attached considerably below the middle of glume which it equals 
or slightly exceeds. The leaves are much narrower than the ligule, 
which is 5-8 mm. long, more or less scabrous and remarkable for 
being strongly nerved.
